High frequency chest wall oscillation (HFCWO) is an airway clearance technique that loosens mucus by applying vibrations at different frequencies to the chest wall via a wearable vest. How does HFCWO work? HFCWO devices typically consist of an inflatable vest, connected by hoses to an external generator, that delivers percussion to the chest wall. Rapid and repeating pulses of positive air pressure gently oscillate (squeeze and release) the chest to facilitate mucus clearance.
HFCWO has been proven to clear the lungs of excess mucus, improve lung drainage and thereby reduce lung infections. Electromed, Inc. Awarded Accreditation from the Joint Commission HFCWO therapy is prescribed for patients with retained secretions as a result of either acute or chronic respiratory conditions.
